How to Measure Your Ring Size

Method 1: Measure an Existing Ring (Recommended)

Select a ring that already fits comfortably on your desired finger.
Use a ruler to measure the inside diameter (the distance straight across the inside of the ring) in millimeters.
Match your measurement to the "Inside Diameter" column in our chart above.

Method 2: Measuring Your Finger

Wrap a flexible measuring tape or a thin strip of paper around the base of your finger.
Mark the exact spot where the ends meet and measure that length in millimeters.
Match this length to the "Circumference" column in our chart above.

Pro Tips for the Perfect Fit ✨

Timing matters: Measure your finger at the end of the day when it is slightly larger.
Caught between sizes? We always recommend sizing up for the most comfortable fit.
Wider bands feel tighter: If you are choosing a thicker ring style, consider going up half a size.
Still unsure? We’re here for you. Reach out to our team at support@cofuze.com for personalized sizing advice.

Note: UK and Australian ring sizes are the same. US and Canadian sizes are also identical.

I gifted this to my wife for our anniversary. She loved the 'past, present, and future' meaning behind the three stones. It's so lightweight that she wears it daily without any discomfort. A truly meaningful piece.

I was honestly surprised by how light it is when I took it out of the box (0.69g is really light!). But once I put it on... wow. It feels like wearing nothing at all, yet it sparkles like crazy. It’s my favorite 'zero-pressure' ring for work.

I'm done with gold-plated jewelry that turns green. This has the Au750 stamp inside and comes with a certificate. For this price, getting solid 18K gold is a steal. It has that rich, warm yellow color that only real gold has.

Jessica M.

Verified Buyer

Bought this to celebrate my promotion. I love the 'Past, Present, Future' meaning. It reminds me of how far I've come. The stones are super clear (VVS1) and look just like my real diamonds.

Chloe T.

Verified Buyer

It is very delicate. Because it's hollow gold, I take it off when I go to the gym or carry groceries. But for dinner dates and office wear? It’s perfect. Elegant and shiny.

Olivia P.

The sparkle on these 3 stones is blinding! Under the sunlight, it throws rainbows everywhere. My friends thought my husband bought me a new diamond anniversary ring.

Sarah D.

Verified Buyer

Got the 18K White Gold version. It looks so crisp and modern. It matches my platinum wedding band perfectly. Love that it's solid gold so the silver color won't wear off.

Natalie S.

Verified Buyer

I usually hate wearing rings because they feel restrictive. This Air-Light tech is no joke. I sometimes panic thinking I lost it because I can't feel it, but then I see the sparkle.

Grace H.

Verified Buyer

My 'real' engagement ring is too heavy and expensive for travel. This is my go-to vacation ring. It looks expensive (hello, real gold!) but it's light enough to wear in the heat without my fingers swelling.

Zoe B.

Verified Buyer

It's dainty enough to stack. I wear it with a plain gold band and it looks like a custom set. The hollow design makes it sit highly on the finger, allowing light to hit the stones from the side.

Victoria L.

Verified Buyer

Under $400 for 18K gold? Yes please. I know it's lightweight, but visually it looks like a $1000 ring. Smart engineering.

Hannah W.

Verified Buyer

The box was surprisingly heavy and luxurious, which balanced out the lightness of the ring. The certificates gave me peace of mind. A very premium unboxing experience.

Isabella G.

Verified Buyer

Bought this for my mom. She has arthritis and heavy rings hurt her fingers. She LOVES this because it puts zero pressure on her joints but still looks fancy.

Megan F.

Verified Buyer

I've been wearing it daily for a month (taking it off for showers). Still as shiny as day one. Just be careful not to squeeze it too hard, it's not a solid block of metal.

Rachel K.

Verified Buyer

Love it! ❤️ The trilogy design covers the width of my finger perfectly. It makes my hand look very feminine and delicate. Highly recommend.

David C.

Verified Buyer

She's picky about jewelry (only wears gold). I was nervous about the weight, but she actually prefers it! She says heavy rings annoy her while typing. Score!

James L.

Verified Buyer

Looks way bigger in person. The 3 stones span across the finger nicely. Definitely looks like fine jewelry, not costume stuff. Good buy.

Ryan P.

Verified Buyer

I checked the GRA number online and it's legit. The gold certificate is also a nice touch. Felt safe buying this online. :)

Your Questions, Answered

Details about 18K gold and care.

Is it real gold?

Yes! It is 100% Solid 18K Gold (Au750). It contains 75% pure gold. It is NOT plated or filled. It comes with an authenticity certificate.

Why is it so light (0.69g)

We use advanced 5D Hollow Technology. This allows us to craft a ring with the visual volume of a larger piece using less gold mass. This makes fine jewelry more affordable and incredibly comfortable to wear.

Can I resize this ring?

No. Due to the advanced 5D Hollow Structure, this ring cannot be resized without damaging the form. Please check our size chart carefully to ensure the perfect fit before ordering.

Is it durable?

18K Gold is a timeless precious metal. However, because this ring uses Hollow Technology to achieve its lightness, we recommend treating it with care—avoid crushing it under heavy weights or wearing it during heavy lifting.

Does it come with certificates?

Yes. Every ring includes two authoritative certificates: a GRA Certificate verifying the Moissanite's grading (VVS1/D-Color) and an 18K Gold Certificate guaranteeing the Au750 purity of the metal.
